Description

Technical Field

[0001] The utility model relates to a mounting clip for a dialysate filter, and belongs to the technical field of dialyzer filters. Background Art

[0002] Hemodialysis is widely used in the treatment of uremic patients. It mainly utilizes the principle of a semipermeable membrane to introduce the blood of uremic patients and dialysate into a dialyzer at the same time, so that the two flow in opposite directions on the inner side and the outer side of the fiber membrane wall. Toxic macromolecules in the blood can flow out through the membrane pores to the outer side of the membrane wall and flow out of the body with the dialyzer. At the same time, by means of the solute gradient, osmotic gradient and hydraulic pressure gradient on both sides of the membrane wall, the functions of removing blood toxins, supplementing blood nutrients and regulating the blood pH value can be realized. The dialysate must be processed by a dialysate filter before entering the dialysis machine, which requires an easy-to-operate and stable mounting clip to achieve the rapid installation of the dialysate filter.

[0003] The installation of existing dialysate filters is complex and not easy to operate, and it is very difficult to ensure that the two end interfaces of the dialysate filter and the two Hansen interfaces can be docked with the pipelines on the dialysis machine simultaneously and quickly.

Specific embodiments

[0017] The following further describes the embodiments of the present utility model with reference to the accompanying drawings.

[0018] As Figure 1 and Figure 2 shown, a dialysate filter mounting clip includes a mounting base 23, on which a pair of positioning grooves 5 are provided. The positioning grooves 5 are used to position and install the dialysate filter 6. Near the two ends of the dialysate filter 6, a straight tube type dialysate pipeline 19 and an L-shaped liquid guiding tube 4 are symmetrically provided. Among them, at any end of the dialysate filter 6, the straight tube type dialysate pipeline 19 is perpendicular to the dialysate filter 6 for docking with the Hansen interface 22 of the dialysate filter 6. The L-shaped liquid guiding tube 4 includes a first tube section and a second tube section connected perpendicularly. The first tube section is arranged in the same direction as the dialysate filter 6 for docking with the end interface 12 of the dialysate filter 6. The second tube section is perpendicular to the dialysate filter 6 and parallel to the straight tube type dialysate pipeline 19. The second tube section of the L-shaped liquid guiding tube 4 and the straight tube type dialysate pipeline 19 are both connected to the commutation mechanism 2. Two commutation mechanisms 2 are symmetrically arranged at the two ends of the dialysate filter 6. Each commutation mechanism 2 includes a meshing driving gear 7 and a driven gear 8. Among them, the driving gear 7 is drivingly connected to the straight tube type dialysate pipeline 19 through a horizontal movement module for driving the straight tube type dialysate pipeline 19 to move horizontally. The driven gear 8 is drivingly connected to the second tube section of the L-shaped liquid guiding tube 4 through a vertical movement module for driving the first tube section of the L-shaped liquid guiding tube 4 to move vertically. The driving gear 7 or the driven gear 8 is connected to the return spring 3 arranged on the base 23.

[0019] The horizontal movement module and the vertical movement module can move in the form of a slider and a slide rail, or can move in the form of a linear bearing.

[0020] In this embodiment, the horizontal movement module and the vertical movement module are described in detail with the form of a slider and a slide rail. Specifically, the horizontal movement module includes a horizontal rack 18 meshed with the driving gear 7. The horizontal rack 18 is fixedly connected with a horizontal slider 11. The horizontal slider 11 is slidably connected with a horizontal slide rail 17 arranged on a horizontal base 16. A straight tube type dialysate pipeline 19 is clamped between the horizontal rack 18 and the horizontal slider 11. The vertical movement module includes a vertical rack 10 meshed with the driven gear 8. The vertical rack 10 is fixedly connected with a vertical slider 9. The vertical slider 9 is slidably connected with a vertical slide rail 21 arranged on a mounting base 23. The second pipe section of the L-shaped liquid guide pipe 4 is fixedly connected with the vertical rack 10 through a fixing ring 20.

[0021] Further, as Figure 4 shown, the positioning groove 5 includes an auxiliary positioning block 14 clamped at the end of the dialysate filter 6. The auxiliary positioning block 14 is provided with a groove adapted to the shape of the end of the dialysate filter 6 and a U-shaped groove 15 adapted to the Hansen interface 22. The dialysate filter 6 is pushed into the positioning groove 5 along the notch direction, and the positioning can be realized, and the operation is convenient.

[0022] Further, as Figure 3 shown, the inner wall of the end of the first pipe section of the L-shaped liquid guide pipe 4 is provided with a stepped hole. The end interface 12 of the dialysate filter 6 is in a stepped shape and is inserted into the stepped hole. A sealing ring 13 is installed at the step. After extrusion, the sealing ring 13 is deformed to achieve a sealing effect.

[0023] The implementation process of the utility model:

[0024] First, the dialysate filter 6 is pushed into the positioning groove 5 along the notch direction for positioning;

[0025] An operation handle 1 is installed on the driving gear 7. By pulling the operation handle 1, the return spring 3 provides a pulling force. At the same time, the operation handle 1 drives the driving gear 7 and the driven gear 8 to rotate. When the driving gear 7 rotates counterclockwise, the driving gear 7 drives the horizontal rack 18 to move to the right. The horizontal slider 11 plays a horizontal guiding role and carries the straight tube type dialysate pipeline 19 to move to the right. At the same time, the driven gear 8 will rotate clockwise in the opposite direction, and the driven gear 8 drives the vertical rack 10 to move upward. The vertical slider 9 plays a vertical guiding role and carries the L-shaped liquid guide pipe 4 to move upward. At this time, the release of the reversing mechanism 2 is realized;

[0026] When the operating handle 1 is released, the operating handle 1 is reset under the pulling force of the return spring 3. At this time, the driving gear 7 will rotate clockwise, and the driven gear 8 will rotate counterclockwise, thus realizing the clamping of the reversing mechanism 2.

[0027] When the reversing mechanism 2 is clamped, the straight dialysis fluid pipeline 19 is docked with the Hansen interface 22 of the dialysis fluid filter 6, and the first pipe section of the L-shaped liquid guide pipe 4 is docked with the end interface 12 of the dialysis fluid filter 6.

[0028] After the dialysis fluid filter 6 is used up, by pulling the operating handle 1, the reversing mechanism 2 is loosened, and the dialysis fluid filter 6 is taken out.
